side of the casing, with the door normally held shut by the coiledspring 25 mounted on the rod. The outer end of the hinge rod has alcrank 26, coupled by connecting rod Q7, with a foot treadle 28, which ispivotally mounted on the end of the casing. vWhen the operator depressesthe foot treadle, the hinge rod 23 is rocked to open the door 7.

This door 7 is provided with a slot 29 in itslower edge which slot iscovered by a flap hinged to the door. Below the door 7, and opposite theopening 6 is the door 8 which is secured to the pintle 31 pivoted inclips 32 on the casing and one end of this pintle has a crank to whichis secured a coiled spring 33 with the other end secured to the case sothat the door 8 is held shut by spring tension, a handle 34 beingprovided to open the door.

rlhe lower compartment containing the ash can 19 is also provided with acasing door 35 hinged at 36 and opened by handle 37.

The crank 17 for rotating the sieve is nore mally held in horizontalposition, as shown in Figure l, by a pivoted latch 38 (Figures 10 and11), which can be turned outwardly to engage and lock the crank orturned down so as to release the crank and permit its operation. Asheretofore stated the weight 12 also tends to hold the crank inhorizontal position with the openings 5 and 6 in register with the doors7 and 8. Y

rlhe mode of operation will'be obvious from the foregoing description.The opera tor fills his shovel, illustrated at l10, with ashes and withhis foot depresses the treadle QS, which opens the door 7 and allows theshovel to loe inserted through the opening 5 into the sieve receptacle.The operator then releases the foot treadle and the door closes allowingthe shank of the shovel to enter the slot 29. Then the operator dumpsthe ashes by turning the shovel as shown in Figure 9. In this turningthe shovel, there is no interference with the shaft 13 by reason of itsdownward bend, and this bend also enables ine to locate the door openinglower and in a more convenient position for the user. The ashes beingdumped, the shovel is withdrawn, the door swinging outwardly to pass theshovel and then autoinatically closing. The operator than rocks orrotates the sieve shaking out all the fine Y ashes, which pass theperforations or mesh and are received in the ash can 19.

rlhe operator then opens the door 8 and. shovels out any large or halfburnt coal forv rehurning. When the ash can 19 is filled by opening thedooi 35, the can may be readily removed by the handle 20.

Having thus described my invention, what Y closed outside casing with asifting receptacle mounted therein adapted to be agitated and acontainer below the sifter to receive the sifted material, the siftingreceptacle provided with openings in its end wall, one above the other,and the casing having doors to cover the openings, the upper door hingedat the top to open outwardly, with means for causing the receptacleopenings to register with the door openings, when the machine is atrest.

2. ln a device of the character specified, a closed outside casing witha rotatable sifting receptacle mounted therein adapted to be agitatedand a container below the sifter to receive the sifted material, thesifting receptacle provided with openings, one` above the other, and thecasing having doors to cover-the openings, with means for causing thereceptacle openings to register with the door openings, when the machineis at` rest.

3. 1n `a device of the character specified, a closed outer casing, ashaft journaled in the sides of the casing with a cylindrical sift ingreceptacle mounted on the shaft, o enings in the Vend wall of thesiftei., one a ove the Vother on either side of the shaft, with doors inthe casing to register with said openings when the machine is at rest,the

upper door hinged at the top to open outwardly and slotted at its freeedge to receive the handle of a shovel, when the door is closed with aflap hinged to the door to close the slotted opening. i

4. In a device of the character specified, a closed outer casing, ashaft journaled in the sides of the casing with a cylindrical sift` ingreceptacle mounted on the shaft, openingsy in' the end wall of thesifter, one above the other on either side of the shaft, with doors inthe casing to register with said openings when the machine is at rest,the upper door hinged at the top to open outwardly and slotted at itsfree edge to receive the handle of a shovel, when the door is closedwith a Hap hinged to the door to close the slotted opening, with aflattened portion for the cylindrical receptacle in line with the loweropening for the reception of non-siftable material.

In a device ofthe character specified, a closed outside casing with asifting receptacle mounted therein adapted to be agitated and acontainer below the sifter to receive the sifted material, the siftingreceptacle provided with openings, one above the other, and the casinghaving doors to cover the openings, the upper door hinged at the top toVopen outwardly and a foot treadle with connection therefor to the upperdoor, for opening saine for deposit of ashes in the sifting receptacle.

6. ln a device of the character specified, a

closed outer casing, a shaft journaled in the sides of the casing with acylindrical sfting' receptacle mounted on the shaft, openings in the endWall of the sifter, one above the other on either side of the shaft,with doors in the casing to register With said openings when the machineis at rest, the upper door hinged at the top to open outwardly andslotted at its free edge to receive the handle of a shovel, when thedoor closed with a flap hinged to the door to close the slotted opening,the shaft of the sifting receptacle being formed With a loop to perinitthe turning of the shovel to dump the ashes.
